Last year, my wife suffered a severe stroke and since that time she is almost unable to read books normally. Reading books was her biggest hobby.

After much experimenting we finally got some progress with the help of Calibre's ebook-viewer program. By carefully tweaking style sheets I can get results in terms of font, font size, line spacing, margins and so on; results that allow her to really read a real book for some 10-15 minutes, which is a great win already.

She uses a touchscreen PC (Tellus 3+ running Windows XP SP2) as a communications device and I would like to tweak the ebook-viewer a bit to make it more suitable for a touchscreen device. Note that (also due to the stroke) she is not able to click small buttons or use a stylus, and she cannot read standard dialogs. Also, the Tellus has no keyboard and no mouse.
